orginal:
number of coins for Azam = 3x
number of coins for Eddie = 7x
Eddie gave 42 coins to Azam
Azam now has 3x + 42
Eddie now has 7x - 42
but 7x - 42 = 3x + 42
4x = 84
x = 21
So at first
Azam had 3(21) or 63
Eddie had 7(21) = 147
number of coins for Azam = 3x
number of coins for Eddie = 7x
Eddie gave 42 coins to Azam
Azam now has 3x + 42
Eddie now has 7x - 42
but 7x - 42 = 3x + 42
